There are a few easy options which require no CSS or code to make the functionality appear. This is one where it exists but is turned off by default and can be turned on and then is as simple as a checkbox to enable on any menu option.
To enable the ability to open into a new tab in the menu:
- Open Appearance
- Select Menu
- In The Top Right Click On [ Screen Options ]
- Now in the drop-down area click the box for [ Link Target ]
- Now you can close [ Screen Options ]
- Now when you go to the menu click to open any item and you will see a new checkbox for [ Open In a new tab ]
With this enabled, you can now route things in your menu to places like YouTube, Social Networks (If you do them) or anyplace where you need them to go but you don’t want them to leave your site.
